Diet

Young fish in rivers eat mainly insects. At sea they first eat tiny drifting crustaceans, then larger prey such as jellyfish, squids and fishes.

Behavior

It lives in the ocean or lakes and returns to its home river to spawn. Young fish stay in deep parts of rivers and become territorial, and at sea they first stay near the coast before moving farther out.

Find it

Where, when and how deep to look.

Where to find it

Found from Central & Northern California and Oregon & Washington.

Habitat

Ocean off Oregon and Washington, the Strait and Puget Sound; rivers from Northern California north.

Depth

From the surface down to 820 ft (250 m).

Fishing depth

20–150 ft trolling offshore, following the bait; shallower in bays and river mouths.

Best season

Ocean fishing in summer; river mouths and rivers from late summer through fall. Seasons are short and set every year.

Best time

First light is best.

Best tides

In river mouths and estuaries, the incoming tide brings fresh fish in.

Best weather / conditions

Calm seas offshore; cool, overcast days inshore.

Bait & gear

What to tie on and what to throw.

Best bait

Herring and anchovies.

Best artificial lures

Hoochies, spoons and bucktail flies trolled fast near the surface; spinners in the rivers.

Tackle setup

8½–10½ ft salmon (mooching) rod with a level-wind or mooching reel; downriggers or divers to get deep.

Hook size

Barbless 2/0–5/0 hooks where required; herring rigs, hoochies and spinners.

Line

20–30 lb mono.

Leader

20–30 lb fluorocarbon, 4–6 ft behind a flasher.

Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Ocean off Oregon and Washington, the Strait and Puget Sound; rivers from Northern California north.
  2. Rig up: 8½–10½ ft salmon (mooching) rod with a level-wind or mooching reel; downriggers or divers to get deep. 20–30 lb fluorocarbon, 4–6 ft behind a flasher.
  3. Pick your bait: Herring and anchovies. Lures: Hoochies, spoons and bucktail flies trolled fast near the surface; spinners in the rivers.
  4. Fish it: Troll faster and shallower than for chinook, often with no weight at all; watch for birds and bait.
  5. Time it: First light is best. In river mouths and estuaries, the incoming tide brings fresh fish in.
Fishing techniques

Troll faster and shallower than for chinook, often with no weight at all; watch for birds and bait.

BigJoe's tip

Coho love speed and flash — when they're in, troll fast in the top 30 ft.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Excellent eating — one of the best-tasting fish in its range.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Mild, orange meat, a bit leaner than chinook: grill, bake or smoke.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

River bars can be deadly — check the bar report and Coast Guard restrictions before crossing.

Regulations

Many areas allow only hatchery coho (with a clipped adipose fin) to be kept. Seasons are set each year. Check ODFW or WDFW. Licenses, size and bag limits and seasons are set by each state — the California Department of Fish and Wildlife (wildlife.ca.gov), Oregon Department of Fish and Wildlife (myodfw.com) and Washington Department of Fish and Wildlife (wdfw.wa.gov) — together with NOAA Fisheries and the Pacific Fishery Management Council. Rules change often, and many areas are no-take marine reserves: check before you go.

Conservation

Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
